Minor flap over the price difference between regions leads the developer VectorCell and publisher Lexis Numérique to offer fans the opportunity to vote how much the upcoming downloadable survival game will cost.

It all started when the pricing for Amy was announced for PSN and XBLA in the U.S.: 800 MS Points ($10) and $12.99 for PSN. Apparently, Amy will cost about €10 in the EU while maintaining its 800 MS Point price, with the PSN price representing the exchange rate between the Euro and the dollar.

Some fans were still a little put off by the price difference between regions and so the publisher and developer decided to hold a little poll. While they've set up a Facebook voting page, Amy is now listed at £7.99 on the game's official site, and you have until January 9th to weigh in on whether the PSN version gets a cross-regional price drop, bringing the U.S. release down to $9.99.

How a price change will affect the release is unknown, but it's set to come out January 11th for both platforms.

The game was developed by Flashback creator Paul Cuisset. Here's the synopsis for Amy:

The game takes place in December 2034 when the global warming has taken effect, spreading diseases and natural disasters around the world. The small town of Silver City (Midwest, USA) has been directly affected by a comet that has come crashing down. When Lana regains consciousness, everything around her is just mayhem. Violent outbursts, fury, rage, wreckage and death: the world she knew seems to have torn to Hell. As if struck by a mysterious virus, most of the ones she knew have now become part of a wild horde. Despite her wounds, she knows she must run as far as possible to escape this nightmare: the viral process has begun inside her but she refuses to become one of them. The presence of Amy, an enigmatic eight-year-old autistic girl with strange powers, who seems defenseless, will force her to make choices that will change both their lives. Infected humans, grisly creatures, Special Forces and even other survivors: they will have to trust and help each other to escape their pursuers in their attempt to survive.
